Vasarely inspired Malte Tonneau Dual Time dial?

I had never paid close attentionto the guilloche on the dial of the Malte Tonneau Dual Time just considering it as a diamond shaped patter. A few days ago I got to spend some time with one and upon closer attention the dial guillochage is not at all "only" a diamond shape but rather a rather complex cubic pattern which reminds me somewhat of those in Vasarely's paintings.

The fact that there are different guilloche patterns one one surface (as in different patterns in different subdials) the guillochage of this dial is not only extremely difficult to do but also extremely time consumming!!

Kudos to the guillocheur Vasarely inspired Malte Tonneau Dual Time dial?

I'll let the pictures speak for themselves...

Q*bert was a great game, and VC's guillochage is superb

That's the name of the game

I was racking my brain trying to remember that.  Thanks Veillotron and fine picture Alex

LoL, I am agree with you, and I love this game in my youth ^^

Might be!
05/02/2008 - 16:48

But beside from the guy who inspired it, I find fantastic to discover such guilloché if you look really carefully the dial, otherwise you do not suspect it.

Hats off to the guy (s) or ladies, who manage doing it.

the guilloche is abslutely stunning! 3 different patterns!! NT

I have never seen it like this before!

It's really magical

Never heard of Vasarely before until a few weeks,

when I was offered some lithographies by him!

Now I looked him up, and seen his art,

very special and fresh! 

This leads me a bit aside, but it's Friday so take liberty!

I have a faiblesse for Oscar Reutersvärd and his "impossible figures",

and they are also geometrical.....

A close friend of mine since many years, where friend of Oscar,

who passed away, 86 years old, 2002.

I have some of his works in original,

his lithographies are sought after and he is most appreciated in Japan,

but still affordable, so this it could be a tip, if you like him

What very few people know is what my friend has told me,

that all the paintings as those above, or the lithographies, are made by hand, without any ruler ! 

And the most faschinating of all, nearly all of his works are made aboard trains !!

I whish you all mu friends,

a very pleasant weekend


All based on optical illusion!

The most extraordinary is that he did it without any ruler!? Unbelievable!

Alex, is the pattern not machine-made?
05/02/2008 - 18:45


no, it's done by hand using an engine
05/02/2008 - 19:21

turning machine like the one in Kazumi's scan below:

The guillochage is applied by engine turning...
05/02/2008 - 19:25

While I am not an expert on the subject, I can tell you that they do not use stamping machines or the like.  The guillochage on each dial is etched out using a machine like this and it takes anywhere from one day to several days to finish a single dial depending on how complicated the pattern is. 

Hope this helps.



Dear Kazumi, what is the Timepiece on this young wirst?

Bonjour mon ami.

I have no idea but I am pretty sure it was not a VC.

Have a great weekend!

Bon week-end à toi aussi (mine will be very very serious) (nt)

Here are a few more pics.

This man's name is Supachai Wattanakantham, probably one of the finest guillocheurs anywhere!

Yes Joseph, the team at VC consider Supachai as being one of the

OMG, that IS incredible!

How is Overseas dial pattern made?
05/02/2008 - 20:30

Is the Overseas dial pattern stamped or is it made by using the engine as well?



its stamped contrary to what I....
05/02/2008 - 21:35

had answered to the same question a few months back where I had written that it was machine engine turned. The reason for this is that it seems that the explanation was lost in translation.

So the final answer is that the Overseas dial is stamped.

Re: its stamped contrary to what I....

Hi Alex,

According to the virtual catalogue on the VC website, it describes the Overseas Dual Time dial as "engine-turned".  Sorry if I ask you to repeat what you may have mentioned already in a previous thread, but I would just like some clarification:

I understand there might be a significant difference between hand-cut and engine-turned.

When you say the dial is 'stamped', do you mean it is cut by a computer aided machine or similar, and not by the skilled hand of a guillocheur using the tools shown above?  Or do you mean it really is a cheaper and simple process of a 'stamp' pressing resulting in a patterned dial?  The latter would leave me a bit disappointed...

Thanks for your clarification!

Best regards


Hi James I think the term "engine-turned" has come to describe any
05/03/2008 - 15:15

pattern cut into a dial whereas technically engine turning requests the machine shown above.

The Overseas dials are stamped by pressing a pattern into the dial, it is ofcourse a cheaper solution but unfortunately watches at the price point of the Overseas often have stamped dials (ie Royal Oak, Nautilus) as hand engined turned dials are really expensive :a dial with a "simple" pattern costs about CHF 3000 (this is an average price given to me from different brands)!

Dear Alex,

Thanks so much for clearing that up! 

By the way, when you mention the AP Royal Oak, they produce an almost identical Dual Time model that looks much too similar to the VC Dual Time for my liking. 

Am I wrong by assuming it also shares the same JLC ebauche that is used for the 1222 movement?  I mean, AP didn't even bother with changing the layout of the watch face at all...(or was it VC that copied AP?) 

Would you happen to know who had the earlier design? Please tell me it was VC! Haha...!?  Do AP and VC have a shared design team?  Or is outright copying acceptable amongst the watch maker fraternity?

Otherwise yet another (small but annoying) disappointment in my otherwise beloved VC Dual Time...

Best regards to you,


I also find the ressemblance more than surprising even though
05/04/2008 - 01:18

I prefer the VC! I may be wrong but I think both were launched the same year!!!

Re: I also find the ressemblance more than surprising even though
05/04/2008 - 01:52

Dear Alex!

Yes, My preference is also the VC.  The lines are more elegant and it seems more balanced. 

Thanks so much for your thoughts!

Best regards


both were launched in 2006!! (nt)

The caliber is not bad either; the 1222 caliber is the smoothest one I have when I turn the crown to set it.
